Step 322: 70620 + 220 = 70840
Step 323: 70840 + 220 = 71060
Step 324: 71060 + 220 = 71280
Step 325: 71280 + 220 = 71500
Step 326: 71500 + 220 = 71720
Step 327: 71720 + 220 = 71940
Step 328: 71940 + 220 = 72160
Step 329: 72160 + 220 = 72380
Step 330: 72380 + 220 = 72600
Step 331: 72600 + 220 = 72820
Step 332: 72820 + 220 = 73040
Step 333: 73040 + 220 = 73260
Step 334: 73260 + 220 = 73480
Step 335: 73480 + 220 = 73700
Step 336: 73700 + 220 = 73920
Step 337: 73920 + 220 = 74140
Step 338: 74140 + 220 = 74360
Step 339: 74360 + 220 = 74580
Step 340: 74580 + 220 = 74800
Step 341: 74800 + 220 = 75020
Step 342: 75020 + 220 = 75240

So, 220*342 = 75240
